When using hci_test the device is stuck after calling Send_HCI_LE_SetExtScanEnableCmd

At some point the messages stop arriving and when a new command is sent from the HCI tester to the device it can result in one if the two option

1. the UART sends all the "leftover" messages and I can continue with other commands
2. I still don't get messages from the device and if I try to send another command I go to the read callback function but I'm not able to reach the command I'm trying to execute

when using loki/develop there is a need for another fix to see the adv report - in hci_test_app.c:: HCI_TestApp_Queue_ProcessCbkEvent replace if (pRec == NULL) with if (pRec != NULL)
